Dietary supplementation with 15% tomato pomace (Solanum lycopersicum L.) improves sperm production and antioxidant status in aged male broiler breeders
Bibliographic record
Abstract
• T-15 increased total PUFAs and reduced n-6/n-3 content in sperm FA profile. • T-15 improved testes' antioxidant status by increasing expression of Nrf2 . • T-15 increased testes’ histological indices by increasing expression of AKT1 . • L-10 treatment reduced histological indices and antioxidant status of testes. The objective was to investigate effects of dietary tomato pomace ( TP ) and L-Arginine (L-Arg; 10% above nutritional recommendation) in aged male broiler breeders. Thirty male broiler breeders (Ross 308), 58 wk old, were randomly and equally allocated into five experimental groups: basal diet ( C ); 5% TP-supplemented ( T-5 ); 10% TP-supplemented ( T-10 ); 15% TP-supplemented ( T-15 ); and L-Arg supplemented ( L-10 ) groups. In contrast to the Control and TP-supplemented groups, sperm of L-10 roosters had higher C14:1, C16:0 and C18:1 n-9c proportions, total saturated fatty acid ( FA ) contents, and n-6:n-3 ratios, but a lower C22:4 n-6 content ( P <0.05). However, sperm of T-15 roosters had increased C18:2 n-6, C22:6 n-3 and total unsaturated FA contents but reduced n-6:n-3 ratios compared to Control birds ( P <0.05). Additionally, serum of T-15 roosters had lower cholesterol and triglyceride ( TG ) concentrations, along with decreased aspartate aminotransferase ( AST ) activity ( P <0.05). In serum of T-15 and L-10 roosters, there were increases ( P <0.05) in total antioxidant capacity ( TAC ) and uric acid ( UA ) and a reduction ( P <0.05) in malondialdehyde ( MDA ) concentration. The T-15 roosters had higher ( P <0.05) serum testosterone concentration and testes glutathione peroxidase ( GPx ) activity. Superoxide dismutase ( SOD ) content was reduced ( P <0.05) in L-10 roosters. Seminiferous tubule diameter ( STD ) and seminiferous epithelium thickness ( SET ) were increased in all groups fed TP ( P <0.05) and T-10 and T-15 roosters had increases ( P <0.05) in tubular differentiation indices ( TDI ). The T-15 and L-10 groups had higher mRNA expressions of AKT1 and Nrf2 ( P <0.05). In conclusion, in aged male broiler breeders, up to 15% TP supplementation is recommended to improve reproductive performance by enhancing testes histology and antioxidant status.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
